Question

A particle of mass M at rest decays into two masses m₁ and m₂ with non-zero velocities. The ratio of de Broglie wavelengths of the particles l₁/l₂ is –

• A. $\frac{m_{1}}{m_{2}}$
• B. $\frac{m_{2}}{m_{1}}$
• C. 1 : 1
• D. $\sqrt{\frac{m_{1}}{m_{2}}}$

Answer 1

Answer: (C)

1 : 1

Answer 2

P₁ = P₂ = P

$\frac{\lambda_{1}}{\lambda_{2}}$ = $\frac{P_{2}}{P_{1}}$= $\frac{P}{P}$ = 1
